Borrowing from Dan Kennedy's teachings...

A 4-piece mailing over a period of 45 days to a target market that your friend can afford to market to. Would cost $2 to $3 per prospect. Of course the success of this would depend upon:
1. The offer.
2. The copywriting.

Since almost every family has at least one person that needs glasses the target market could be geographical. Try it on 100 prospects (total cost $200 to $300).

The first contact could be an endorsed piece from an partnering merchant.

This type of direct mail program does work. Plus you can do as much as you can afford to do.

Take care,
